Atypical positioning of the baby for delivery is very rare. Usually, around the 32nd week of pregnancy, the baby receives the so-called the starting position in which it will be born. The longitudinal head position is the best. However, sometimes the baby adopts an unusual position for delivery, which forces the pregnancy to be terminated by caesarean section. Why is this happening?
Atypical position of the fetusmay have variousreasons . The most common cause of improper positions of the fetus is the abnormal structure of the future mother's bone pelvis. When the pelvis is non-standard (e.g. when it is too small or too long and too narrow), the child has no place to posture in the normal way - this is the most common cause of transverse and oblique positions.
Unusual baby positioning: reasons
- preterm labor (when a child is born, who has not yet managed to change to the head position)
- abnormal structure of the uterus (e.g. uterine septum, bipedal uterus)
- polyhydramnios - increases the baby's mobility
- low water - restricts the child's mobility
- flaccid walls of the uterus and abdominal wall - as a consequence of numerous deliveries (may occur in women who have given birth more than three times)
- birth defects of a child (e.g. hydrocephalus)
- front bearing
- umbilical cord too short
- presence of tumors, fibroids in the uterus
- twin pregnancy
How are the twins arranged?
In the case of a twin pregnancy, the positions of babies may be different - there are many variants. Natural delivery is possible only in two situations - when both babies are placed in the head or when the first is placed in the head and the other in the buttocks. Any other location is an indication for a caesarean section.
Outer baby head rotation
When your baby is in a pelvic or oblique position, your doctor may suggest external uterine rotation to avoid cesarean delivery. It lasts a few minutes: the obstetrician with massaging and pressing movements tries to move the baby to the position with its head downwards. The procedure is performed in a hospital with an operating room - so that a caesarean section can be performed in the event of the commencement of labor.External rotation is best done after the 36-37 week of pregnancy, a few days before the planned delivery date. The effectiveness of the treatment is approx. 50%. in primiparous women and 60 percent. in multiparous women. Success is favored by a greater amount of amniotic fluid (but not polyhydramnios!) And a complete pelvic position (one in which both legs are bent at the hips and knees, and the fetal feet are at the bottom).
